A group of four minivans recently tested by the Insurance Institute for Highway Safety for protection in small overlap front crashes showed some of the worst possible outcomes for this type of crash, with only one vehicle performing acceptably.The Nissan Quest, the Chrysler Town & Country and its twin, the Dodge Grand Caravan, all earned poor ratings.READ: Minivan crash report studyThe exception was the 2015 Toyota Sienna, which earned an acceptable rating. It joins the Honda Odyssey, which last year earned a good rating in the test, in the ranks of TOP SAFETY PICK+ winners."Minivans are popular among parents, a group that tends to be safety conscious, but we’ve only seen two so far that offer decent protection in small overlap crashes," says David Zuby, IIHS executive vice president and chief research officer.In the small overlap test, which replicates what happens when the front corner of a vehicle collides with another vehicle or an object such as a tree or a utility pole, the crash forces bypass the vehicle's main energy-absorbing structure.These crashes may be especially difficult for minivans to handle. That's because minivans are typically built on car platforms but are wider than cars. As a result, more of the vehicle is located outside the main structure. Minivans also are heavier than cars.

All flights in and out of Chicago's two airports were halted Friday morning because of a fire at a suburban Chicago air traffic control facility. The ground stop threatened to send delays and cancellations rippling throughout the nation's air travel network.

By 8:30 a.m., more than 580 flights at O'Hare and Midway had been canceled, according to aviation tracker FlightAware.com. FlightAware.com CEO Daniel Baker said the number of cancellations and delays are expected to rise considerably over the next few hours.

An Italy-bound flight was forced to return to London when a piece of its wing collapsed Thursday and video of the incident was posted to Facebook and YouTube.

A journalist for The Independent in London was on the flight and reports that passengers were "terrified" after hearing a loud band shortly after take off from London City Airport.

The owner of online travel agency To Tuscany also posted the dramatic video of the City-Jet flight bound for Florence. The Avro RJ85 aircraft landed in London safely and passengers are now en route to Florence on another aircraft.

To Tuscany posted the video on its Facebook page, saying it was from the owner. While the post does not specifically name the owner, the company's web site lists the owner as Sean Caulfield.

"On take-off there was a strange noise then a bang and six-foot plus section of the left wing that looked like suddenly came loose and hung down, flapping in the jetstream," journalist Cole Moreton told The Independent.

In response to the tweet City of Seattle communications director Jeff Reading released a statement:

“It’s never acceptable for a city employee to ridicule members of the public. I understand the tweet in question was meant humorously, but many — myself included — took it quite differently. Mayor Murray holds a high standard of respect for communications with the public across all city departments. We will ensure that this type of offending humor is not repeated in communications to the public by City of Seattle employees.”

Officials with the West Seattle Transportation said the tweet was inappropriate and unprofessional.

SDOT spokesman Rick Sheridan released a statement after the tweet:

“The use of the hat meme was not intended to insult drivers but to highlight a roadway problem and help drivers make decisions about their trips. We apologize to anyone that was offended by the tweet.

Our traffic management center personnel typically use humorous memes to highlight problematic situations for drivers. The staff member was trying to note that rubbernecking near a collision site was creating delays.

We have removed the tweet from our Twitter feed. The staff member’s supervisor will also reinforce the department’s standards for social media. Again, we apologize if anyone was offended.”

A marine exploration company has claimed it’s found wreckage in the Indian Ocean consistent with that of a commercial airliner.

“We’re not trying to say that it definitely is MH370, however it is a lead we feel should be followed up,” GeoResonance spokesman David Pope told Australia TV station 7News.

The location of the company’s sighting is nearly 3,000 miles north of the official search zone in the southern Indian Ocean.

According to the GeoResonance website, the company’s geophysical survey methods have been used to identify WWII munitions that later led to the recovery of explosives left buried under layers of silt in the coastal Black Sea.

According to CNN, Malaysian Acting Transportation Minister Hishammuddin Hussein said Malaysia "is working with its international partners to assess the credibility of this information."

However, the agency responsible for coordinating the multinational search in the southern Indian Ocean dismissed the claim.

“The Australian-led search is relying on information from satellite and other data to determine the missing aircraft's location,” the Joint Agency Coordination Centre (JACC) said in a statement reported on CNN.com. "The location specified by the GeoResonance report is not within the search arc derived from this data.”

Pope told 7News GeoResonance experts compared recent findings with images taken on March 5, three days before MH370 was reported missing.

“The wreckage wasn’t there prior to the disappearance of MH370,” Pope said.

There’s no indication the JACC will investigate.

“The joint international team is satisfied that the final resting place of the missing aircraft is in the southerly portion of the search arc,” the agency said according to a CNN report.
